Data and code for: Assessing boundary discontinuities in environmental protection systems in Cundinamarca, Colombia, using NDVI and spatial regression discontinuity
Abstract
This repository contains the data, scripts, and processed outputs supporting the manuscript “Assessing boundary discontinuities in environmental protection systems in Cundinamarca, Colombia, using NDVI and spatial regression discontinuity”. The repository includes Google Earth Engine scripts used to generate annual Landsat-derived NDVI composites for 2015, 2017, 2022, and 2024; Stata do-files used to estimate annual spatial regression discontinuity models, difference-in-discontinuities models, placebo cutoff tests, density continuity tests, and manuscript figures; processed analytical datasets; statistical output tables; and figure files. The study evaluates localized boundary-level differences in vegetation condition across multiple environmental protection systems in Cundinamarca, Colombia, including protected areas registered in the National System of Protected Areas, Indigenous reserves, and Payment for Ecosystem Services schemes. The empirical approach uses institutional boundaries as geographic thresholds to compare NDVI values for pixels located immediately outside and inside protection systems. The repository is intended to support transparency and reproducibility of the analyses reported in the manuscript. Users should consult the README file and data dictionary for details on file structure, variable definitions, software requirements, and the recommended workflow for reproducing the results.
